To all whom'it may concern:

Be it known that. I, ARNOLD GULDEMANN, a citizen of the United States, residing in Paterson, Passaic county, New Jersey, have invented certain new and useful Improvements in Loom-Shuttles and I do hereby declare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon,

' The object of this my present invention is to provide an im roved means for preventing the .cop or quil in a shuttle from slipping lengthwise on its spindle when the latter is in the depressed position, which means, however, shall be inactive when the spindle is in the raised position. v

In view of the foregoing, my invention consists in providing a serrated or toothed' strip arranged substantially longitudinally in the spindle and movable therein toward and from its axis, and means, operative on oppoto'move in the spindle, according as the. latter-,is in the raised or depressed position, wherebyto sheath or unsheath its teeth or serrations or otherwise eflfect a disengageserrations and the bore of the quill or cop.

My invention consists also in pivoting the causin the same to be raised when'thespindie is epressed and to thus project its teeth or serrations and providing additional means for limiting the upward movement of the strip in the spindle at this time.

The invention will be found fu'lly illusshowing-one form of my improvement; Fig. 2 1s a plan view of the spindleand strip of Fig.

illustrating another form of my improvement.

-Referring, first, to F i s. 1 and 2: in the theusual manner, the spindle c. Said spindle'is formed with a longitudinal slit d so shaped at the butt-or pivote1 1d of the spindle as to produce an overhang or projection e. f is the usual plate spring held under tension by the pins 9 and so acting on the spindle as to hold it elevated or depressed. his a strip having its top edge toothed or serrated, as at i, and pivoted on a pin it near its outer end in the spindle in the .slit (Z thereof in such manner as to be movable toward and away from the longitudinal axis of the spindle; at its free end and on its lower edge is formed a 111 j. in the spind e so that it may not move therein on its pivot unintentionally. When the strip is elevated, i. e., in the full-line position shown in'Fig. 1, its teeth or serrations project from the spindle and may thus engage the bore of a' cop or quill whereby to hold the latter against slipping on the spindle; when the strip is depressed, its teethorserrations disengage or clear'the bore of the cop or quill, which may thereupon be removed without hindrance. The strip is depressed when the spindle is, elevated, and, vice versa, it is elevated when the spindle is depressed, and this is accomplished in the present instance by roviding two stops or pins k and Z .stance shaped to form a seat 71. for "a small spiral spring 0. p is the serrated or toothed strip pivoted in said slit near its outer end and formed at its inner .or free end with an extension g which rests on said spring and has an integral downwardly extending pintle fitting into the spring to keep the parts in proper operative position. Above the said inner end of the strip is a stop or stop pin 8 .mounted in the shuttle in such position as to be only engaged by the extension q when the same is raised; one. function of this stop is to prevent the strip from becoming disengaged, as regards its pintle, from the spring 0. In this instance, when the spindle is elevated the extension q brings up against the stop s,

so that its teeth or serrations will be disengaged from the cop or ,quill when the sp'm Said strip fits rather snugly 65 3 the strip will be elevated, whenever not depressed by the stop 8, without regard to spring I Having thus fully described my invention, what I claimand desire to secure by Letters Patent is: v

i. In a shuttle, the combination of the body, a spindle pivoted therein, a strip arranged substantially longitudinally in the s indle,said strip being toothed or serrated a ong one edge and movable toward and away from the longitudinal axis of said spindle, means for causing said stri to move to depress its toothed or serrated e ge-when the spindle is elevated, and a spring normally tending to raise said strip in the spindle, substantially as described. 1

2. In a shuttle, the combination of the Lody, a spindle pivoted therein, a strip arsmear;

ranged substantially longitudinally in the spindle, said strip'being toothed-or. serrated \along one edge and movable toward and away from the longitudinal axis of said spindle, means for causing said strip. to move to raise its toothed or serrated edge'when the spindle is depressed, and means for limiting v edge thereof, a spring-interposed between said strip and the seat and normally tending to raise the strip in the spindle, and means for causing said strip to move to depress its teeth or serrations, when the spindle is raised, substantially as described. I t

In testimony, that I claim the foregoing, I have hereunto set my hand this 11th day of May 1906.
